Title: Am i going over time?
Post by: aronno on October 24, 2009, 08:42:02 pm
on average the specialist exams;

time taken; (40-50mins for multi-choice) average mark out of 22 => 17
short answers (70 mins maximum) average mark 48/58

(overall percentage average is 76%

any advice on the time taken to complete multi's and short answer
thanks guys
btw what percentage is needed to get u an A+ for the exam

50 minutes for multiple choice is way too long, it should be done in about 20-30 minutes.

yeah 50 is too much, you need to cut down, I'd say 30 - 40 mins is probs maximum.

but should i risk probably dropping the average mark of 17 to probably 12 etc. for multi choice

Well, think of it this way: 120 minutes. 80 marks. 120/80 = 1.5 minutes/mark.

22 * 1.5 = 33 minutes for multiple choice
58 * 1.5 = 87 minutes for analysis.

Of course, some questions take less time or longer than others, but that's a rough estimate as to how long you should spend :)

It was 82.5% for lowest A+ according to last years statistics btw.

Better than not finishing the exam no? And really, the point is that you need to work harder over the next week so that this doesn't happen to begin with. Besides, you can guess MCQs in the last minute if you don't finish, but you can't guess short answers.

I guess you mean extended response questions but yeah the MC is way too long. I don't really know how you're taking ridiculously long in the MC but not so long in the extended.
I found that MC can be done super quickly and that the extended takes quite a lot of time.

Just do a few more in exam conditions and try to improve the speed without needing to randomly/ridiculously rush to the point your score drops a lot. If you can't improve time-wise, it might be better to do the extended 1st.

btw what percentage is needed to get u an A+ for the exam  

This is my rule of thumb! work out the mark percentage of each section and multiply this by the time to work out how long you should spend.

So you get 2 hours (120 minutes) to do the exam, thus, you shouldn't entend your time inmultiple choice over roughly 33 minutes (any longer is too long), since multiple choice only gives you 27.5% of your total marks. What I recomend you do is do the second section of the exam as there is gift questions, multiple choice questions usually have some ambiguity and this section gives you 72.5% of the total marks. If you say tackle a gift question, you will complete it a lot faster and just seeing a completed section of the exam will boost your confidence right up.

A+ in exam 2 required at least 82%.

say, if anyone has done kilbaha 08, did you find this exam hard, medium or easy. (honest opinion please)
because i thought it was quite difficult.
oh yeah, do you think this is vcaa standard?
Title: Re: Am i going over time?
Post by: TonyHem on October 24, 2009, 11:00:12 pm
Have you done any vcaa ones?
I haven't done that exam but generally Kilhaba is harder than vcaa.

is it just me or are the 2003 -2005 exams(neap, mav etc.) in multi-choice easier than todays standard.
 knida get the feeling it is?

because i planning on competing the multi-choice sections within 30mins (i may have to rush but its a risk ill take) (a good ida or not?)


thanks to the people that have helped me, you guys are awesome. and i truly respect yours actions for giving up some of your time. thanks heaps.

hey guys, i am specifically having trouble with working out the landing angles or launching angle questions. Similar to that of vcaa 07 Q.4 (c)
please help.

You can find the cut-off's on the vcaa website: http://www.vcaa.vic.edu.au/vce/statistics/2007/statssect3.html#H3N10378

And with that question you have to use related rates of change: using .

I believe you dot product the velocity vector with a vector on the ground (get rid of the k component)

thanks BRO!!!
btw i've seen questions use tan(theta) = [(a)^2]/{((b)^2+(c)^2))^(1/2)}
to determine the angle. what does this relate to? or what is the significance
